does jquery have an equivalent of dojo.hitch()?

Question

Forgive my ignorance as I am not as familiar with jquery. Is there an equivalent to dojo.hitch()? It returns a function that is guaranteed to be executed in the given scope.

The function.bind mentioned by bobince is a pretty useful tool. You could use it to rewrite the hitch function pretty simply:

// The .bind method from Prototype.js 
if (!Function.prototype.bind) { // check if native implementation available
  Function.prototype.bind = function(){ 
    var fn = this, args = Array.prototype.slice.call(arguments),
        object = args.shift(); 
    return function(){ 
      return fn.apply(object, 
        args.concat(Array.prototype.slice.call(arguments))); 
    }; 
  };
}

jQuery.hitch = function(scope, fn) {
  if (typeof fn == "string") fn = scope[fn];
  if (fn && fn.bind) return fn.bind(scope);
};

At least based on the doc page you linked, this is how I saw the function working...
